An MMI System - Update must be performed.

1. Connect a recommended battery charger to the designated charging posts in the vehicle.

Note:
To avoid false readings of the battery manager, don't charge the battery directly at its posts.

2. Eject possible inserted CDs from the CD changer in the glove compartment and load Update CD 4F0 906 961 AB in position 1.

3. All sound settings will be set to default after the update. Depending on the installed MMI components, further settings (Previous/Memory station list, stored CD name, directory entries and voice recognition name tags) may be lost.

Tip: Write down all settings to restore them after the update. Inform customers that they have to re-record their name tags.

8. Scroll down the component list with the Central Control knob and select Start download.





9. Note and obey the displayed message to avoid component breakdowns, and scroll down the screen to accept the update with OK.





10. The MMI component date lasts between 15 and 60 minutes, depending on the installed components.





11. After initialization of the updated components, the screen shown (or a similar one) appears.

Note:
The displayed status Not OK and - is update-related and not a fault. Please ignore and proceed.
